Central Nervous System Pdf Brainstem Central Nervous System •carry impulses from the central nervous system •interneurons (association neurons) •found in neural pathways in the central •nervous system, connect sensory and motor neurons. In vertebrates, the nervous system has two divisions: the peripheral nervous system and the central nervous system (figure 1.1). the central nervous system (cns), which consists of the brain and spinal cord, is surrounded by another nervous system called the periph eral nervous system (pns).
The Central Nervous System Pdf Neuron Autonomic Nervous System Nervous system 1. sensory input—gathering information sensory receptors monitor changes, called stimuli, occurring inside and outside the body 2. integration nervous system processes and interprets sensory input and decides whether action is needed 3. motor output a response, or effect, activates muscles or glands © 2018 pearson education, ltd. Two subdivisions of the motor division: neurons: nerve cells specialized to transmit messages called nerve impulses. neuroglia: supporting cells. neuroglia divide whereas neurons do not. • nerves are cable like bundles of axons of the neurons. Central nervous system (cns) the central nervous system (cns) consists of brain and spinal cord. central nervous system functions to integrate information and coordinate majority of physiological activities in bilaterally symmetric animals. several opticsensory system like retina, nerve, the olfactory nerves (1st) and olfactory. Neurons transmit signals from the central nervous system to the effector cells and are sometimes called motor neurons. interneurons connect neurons within specific regions of the central nervous system.

Overall objectives: to understand the histological components of nervous tissue; to recognize the morphological features of neurons; and to differentiate myelinated from non myelinated axons i. basic organization: a. central nervous system (cns)—brain and spinal cord. The central nervous system consists of the spinal cord and brain. the spinal cord is found in the vertebral column and the brain is housed in the cranium skull. Central nervous system (cns) • the cns is made up of the brain and spinal cord. this division of the nervous system controls the regulation of body systems as well as the processing and creation of memories. peripheral nervous system (pns) • the pns is made up of all the neurons connecting the cns to the rest of the body. the pns sends.
